If you have a Hackberry tree or a sago palm you know what I am talking about. Hackberry trees get wooly aphids every June that drip black sooty mold all over everything below the tree. Use Bayer Tree and Shrub Protect & Feed as a soil drench for 9 month insect protection. Since I have been treating my neighbors tree in March or April I have not had to spray to protect my yard, vehicle, or lawn furniture from the soot. If you have sago palms, use it to prevent and kill all the white bugs on the tops and bottoms of the fronds. They are called Asian cycad. This insect has been around since the year before the snow, so be diligent and treat to help rid the city of this pest.
